Update 7/1/23:Very happy with the Omnishelf! Raising my review to 5 stars after using it daily. I love how compact this is in the field as it allows me to eliminate carrying a small foldable table for my laptop. To give this shelf additional functionality, I designed some 3D printed accessories that clip directly to the Omnishelf and fit inside the case when transporting:• Mutlpurpose drink holder that also serves as a multimeter or ammeter holster• Mouse pad shelfCheck for these accessories on Etsy if you are interested. I have a few other 3D designs I may incorporate as well to add more functionality to the shelf.---------------------------------------------------------------------------------------------------------------------------I priced out components to make a custom version and the price of materials came close to the price of the Omnishelf. I didn’t factor in my labor, but I could see it would take some time to implement my ideas so I opted for the price of entry. This shelf is robust and grips great with the magnets. I haven’t tested the suction cups yet, but I keep them on me in case I need in field. I have some additional ideas and modifications that I will create with a 3D Printer that will help make this the Ultimate portable shelf. Only negative is the price of the shelf as I feel this should be cheaper for what it is. You’ll see there are other reviews stating the same.
